Abstract: PURPOSE: A method for automatically correcting the current time is provided to display the current time automatically by receiving time information and extracting the time information in case of changing a channel. CONSTITUTION: A micro processor decides whether a predetermined time is passed after changing of a channel whenever a channel is changed. If the predetermined time is passed, the micro processor decides whether a time automatically setting flag is set for performing a time automatically correcting operation continuously. If a time automatically setting flag is not set, the time automatically correcting operation is completed. If a time automatically setting flag is set, the micro processor decides a data status value included in broadcasting information extracted from a data slicer. If the data status value(PT1-STATUS) is '0', the micro processor completes the time automatically correcting operation. If the data status value(PT1-STATUS) is '1', '2' or '3', the micro processor decides as the data are normally received, the operation responded to each value is performed, respectively. If the data status value(PT1-STATUS) is '1', the micro processor decides as only the data of main channel are normally received, and extracts only the information for a date and time, and judges whether the extracted date is more than a date before a time correction. If the extracted date is not less than a date before a time correction, the micro processor sets the extracted date as the current date. If the data status value(PT1-STATUS) is '2', the micro processor decides as only the data of sub channel are normally received. If the data status value(PT1-STATUS) is '3', the micro processor decides as the data of main channel and sub channel are normally received simultaneously.
